跪求大神帮忙，本人新手

在标签中显示哦

用串口调试助手显示的十六进制数是对的，但转换的时候在上位机上只显示其中一个，要不就报错

这是我们写的代码，能帮我们看看吗？
Private Sub Command1_Click()
MSComm1.Settings = "2400,N,8,1"  '设置波特率4800，无校验位，8位数据位，一位停止位
= 4             '设定串口端口
MSComm1.InBufferSize = 64        '设置接收缓冲区大小
MSComm1.OutBufferSize = 64       '设置发送缓冲区大小
MSComm1.RThreshold = 1          '设置并返回产生oncomm事件的字符数
MSComm1.SThreshold = 0
MSComm1.InputLen = 0             '读取整个缓冲区
MSComm1.InputMode = comInputModeText   '以文本方式接收
MSComm1.InBufferCount = 0       '清空接收缓冲区
MSComm1.OutBufferCount = 0      '清空发送缓冲区
If MSComm1.PortOpen = False Then
     MSComm1.PortOpen = True
     End If
End Sub

哦哦，谢谢，我拿去试试。顺便问一下，上位机与单片机除了串口通信，还需要通信协议吗
